Older network tools often struggle with high-DPI monitors or newer versions of Windows 10 and 11. The v2 update addresses scaling issues, making the interface crisp and usable on modern hardware.

Once you’ve completed the clumsy 04 v2 download, follow these steps:

With Clumsy 04 v2, you have control over several distinct parameters:

The best part? It works on Loopback. This means you can test software running on your own machine without needing an external server.

Clumsy is a unique network conditioning tool that sits between your application and the network adapter. Unlike traditional simulators that require complex scripting or virtual machines, Clumsy works in real-time by intercepting network traffic and applying selected filters. You can simulate:

choco install clumsy --version 0.4.2 (using Chocolatey) often pulls the V2 revision.

The core engine has been tweaked to handle high-bandwidth throughput better than previous versions. Whether you are simulating a 5% packet drop or a massive 2000ms delay, the resource usage remains surprisingly low.

Clumsy is intended for lawful purposes only:

Never use Clumsy to degrade networks without authorization. Doing so may violate computer fraud laws.

You can find the latest binaries on the official GitHub repository or major software archive sites.

(Note: If the application fails to start, ensure you have Npcap installed with the "WinPcap API-compatible Mode" checked during installation.)
